Well I finally got around to pulling my engine apart to find out what happened.
The backstory I was returning from an event somewhere when about a mile from home I hear a awful noise and loud clatter. I had no loss of power and drove the rest of the way home. Rented a trailer and towed to my Mom's and the engine finally got pulled out last year. Time passed and I finally startred to pull it apart. I had been thinking possible connecting rod bushing problem at the wrist pin as I did not rebush those at the time of the rebuild. Well here is the results. Question can the washer be machined out of the head? Is the piston still usable? Opinions welcomed. Attached image(s)

Looks like the piston took the most beating. I would Roloc the worst off the head, try to find a replacement piston and cylinder and run as-is. Somebody has to have a decent piston and cylinder for a 2.0 laying around...
Or you can save the money, look for new everything, replace the heads and pistons/cylinders (wouldn't want to only do 1), do the bearings while you are in there (assuming they start making Type IV main bearings again) and then sometime in 2012 your car will be back on the road... 914's do look sporty when on jack stands (IMG:style_emoticons/default/biggrin.gif) |
